Thought and pleasure; Thought has a great deal to do with pleasure. I can look at that sunset and the next moment it is gone—thought comes in and begins to think about it, says how beautiful it was when, for a moment, “I” was absent, with all my problems, tortures, miseries; there was only that marvellous thing. And that remains as thought, is sustained by thought. The same thing with regard to sexual pleasure—thought chews it over, thinks about it endlessly, builds up images which sustain the sensation and the demand for fulfilment tomorrow. It is the same with regard to ambition, fame, success, and being important.
